My invention relates more particularly to disklike sheet metalstructures as for example and more especially those forming the heads ofreels provided for the winding thereon of electric cable or the like.

My primary object is to provide a construction oi' the character abovereferred to which while presenting the desired strength, stiffness anddurability may be manufactured at less cost and be of lighter weightthan such structures as hitherto provided; and other objects as will bemanifest from the following description.

Referring to the accompanying drawings:

Figure l is a view in elevation of a reel embodying my invention.

Figure 2 is an end View of the reel with a portion thereof broken awayto disclose a detail of construction.

Figure 3 is an enlarged broken longitudinal sectional View of the reel,the section being taken at the line 3 3 on Fig. 2 and viewed in thedirection of the arrows.

Figure 4 is a fragmentary sectional View taken at the line 4-4 on Fig. 2and viewed in the direction of the arrows; and l Figure 5, a similarview taken at the line 5 5 on Fig. 2 and viewed in the direction of thearrows.

Referring to the particular illustrated embodiment of my invention, thereel as shown comprises a hub portion t sho-wn as formed of a sheetmetal drum with its ends inwardly deflected to form annular flanges l',and sheet metal heads 8 positioned at the ends of the hub 6 and securedthereto as hereinafter described.

Each head 8 is formed of spaced apart disk-like sheet metal members 9and it) centrally .apertured as represented at il and l2, respectively,to receive an arbor tube i3 secured in place as for eX- arnple bywelding these parts together as indicated at lll and l5.

The member 9 is shown as formed of a substantially flat sheet metal diskwhich, in the reel construction, constitutes the inner face of the head.

The member i@ comprises an annular series of sheet metal segments i6secured together as hereinafter described and forming in effect asectional disk.

Interposed between the members 9 and l@ are reinforcing ribs il whichradiate from the central axis of the head, these ribs being of wedgeshape as shown in Fig. 3, tapering toward their outer extremities andengaging at their opposite longitudinal edges with the members 9 and I@and in effect forming braces, the head structure thus formed being ofgeneral at cone form as illustrated.

The ribs Il in the particular construction shown are formed integrallywith the segments 5 I5, being provided as flanges extending inwardlyalong the radially disposed edges of the segments. Preferably, and asshown, the flange along one edge of each segment and represented at I8is doubled back as represented at I9 to present an l0 outwardly facingchannel or groove 29 into which the flange on the other edge of theadjacent segment and represented at 2l, extends, whereby each rib I'l isformed of three thicknesses of metal imparting thereto great resistanceto crushl5 ing.

The members 9 and I0 and hub 6 are secured together by tie rods shown asbolts 22 which extend through openings 23 and 24 in the flanges 'l andthe disk 9, respectively, and openings in the segments IS; the heads andnuts provided on these bolts at their opposite ends engaging with theouter members I9, respectively, of the heads 8, as illustrated of thenut 25 in Figs. 3 and 5, to effect the desired clamping action. 25

It is desirable that the heads and nuts on the bolts 22 be insetrelative to the plane of the outer surfaces of the members Il] to avoidundesirable projections thereon, and to this end the portions of themembers l0 at which these head-forming 30 parts of the bolts engage, areformed of embossed washers 26 set into openings 21 in the segments I6and lapping, at peripheral flanges 28 thereon, the walls of the openings2l to which they are secured as by welding them thereto as indicated at29.

The washers 2B are so positioned relative to the ribs il, as shown, thatportions of the flanges 28 of the washers lap the joints betweenadjacent segments I6 and thus extend over the outer edges of the ribs,whereby the stiffness of the ribs Il is availed of in resisting thestresses produced in the tightened condition of the bolts 22.

Reels of this character are commonly rolled I along the iloor and toprovide desirable tread surfaces at the peripheries of the heads Ipreferably curl the peripheral portions of the disks 9 aroundreinforcing metal rings 30, as represented at 3|, with the peripheralportions of the segments I5 50 interposed between portions of the rings30 and the disks 9, and the curled portions 3l and the peripheral edgesof the segments it tack-welded together as indicated at 32.

As will be understood from the foregoing, the

heads 8 while being of comparatively light Weight are highly resistantto the various stresses to which they may be subjected in use tending todistort them, the ribs I'l serving as compression members resistingstresses tending to deflect the peripheral portions of the headyoutwardly and as tension members resisting stresses tending to deflectthese portions of the head inwardly.l

While I have illustrated and described a particular constructionembodying my invention, I do not wish to be understood as intending tolimit it thereto as the same may be variously modied and altered Withoutdeparting from the spirit of my invention. Thus, by way of example, thereinforcing ribs may be omitted, in which case the member l0, of generalconical shape, would preferably be formed either of a single sheet ofmetal or of sections connected together.

What I claim as new, and desire to secure by Letters Patent, is:

A reel comprising a hub member, heads at the ends of said hub member,said heads being formed of spaced apart members and ribs interposedbetween said spaced apart members, the outer ones of said spaced apartmembers containing openings, embossed washers in said openings andhaving flange portions which extend crosswise of adjacent ribs andoverlap the outer edges of the latter, and tie rods connecting t0-gether said hub member and heads and extending into said washers andhaving head portions lol5 cated in said washers.
